To all whom it may concern Be it known that I AUeUsTus Bowsna, a citizen of the United tes of America, and resident of Fort Wayne, in the county 0 Allen and State-of Indiana, haveinvented certain new and useful Improvements in Liquid-Dispensing Apparatus, of which the following is a specifi This inventionrelates to improvements in liquid dispensing apparatus and the object thereof is to aiiord facilities byl means of which gasolene and oils or other 'quids may be dispensed in definite quantities with the necessity of operating a pump.

The object of the invention is accomplished by the construction illustrated in accompanying. drawings, in which 2-- Figure 1 is an elevation showing a general arran ment of parts constituting a complete installation, portions being cut away and in section;

(Fig. 2 is a side elevation in vertical section showing a dispensing head, portions bein cut away; a

Fig. 6 is a detail view showing the by-pass valve arranged in connection with the'supply-pipe and overflow pipe and showing also the operating lever, a portion of the view heinpsin vertical section.

imilar numerals of reference indicate throughout the several views and referring-now to the same:-

1 is a reservoir for holding a supply of liquid, and 2 is an auxiliary tank situated in a plane lower than the reservoir. A. ventpipe 3 has commu cation with the reservoir at the top thereof, and a discharge pipe 4 extends into the reservoir and is provided with a foot-valve 5 at its lower end. A fill-pipe 6 has communication with the reservoir at the top thereof and through which the reservoir corresponding parts is recharged, there being an extension 6' connected with the fill-pipe proper. A drainpipe 7 -has communication with the fill-pipe 6 and s used for the return of surplus liquld. A discharge pipe 8 extends into the an!- iliary tank and has communication with the lower part therpof, and has connection wi the dischargepipe 4 of the reservoir through the medlum of a connecting-pipe 9. A supply-p1pe 10 of the dispensing apparatus has communication through a check-valve 11. The a tank is supplied with liquid from vorr through the pipes 4, 9 and 8 w tron as a siphon, there being an extensionpipe 12 connected w 1th the discharge-p380 4: through whi h the siphon may he prim by suppl mg a sulficient initial quantity of liqu to establish action in the siphon. The auxiliary tank has inpommunication with its upper end an air-pipe 18 through which air-pressure is applied for expelling liquid from the tank the liquid passingout thrpugh the disc rge pipe and check-valve 11 into the supply-pipe 10 when the-pressure is applied. The pig: 13' also serves as an exhaust pipe when t tank is being refilled. The air 1s applied and exhausted through the medium of a controlling mechanism having connection with the air-pipe 13. The controlling mechanism is compri of a communication with manifold 14 ha the air-pipe 13 an also with an exhaust pipe 1?) thro h an escape-valve 16. An air supply pipe 1 has communication with the manifold throng 'a throttle-valvels. The throttle-valve and the esoa erated simultaneously by a actuated iary the reser hich func ever 19 which is by means of an electro-magnet 2 The exhaustipe may if so desired be connected with e vent-pipe 3 so that the latter will convey the exhaust to its final discharge.

B and C are discharge heads through which the liquid is dispensed, and D is a meter having connection with the supply-pi IQ for ascertaininghthe quantity of hqui passing therethroug The particular construction of the meter is immaterial to the present invention as any other suitable meter may be employed instead of that shown. Each of the dispensing heads is comprised of a supe-valve are opwith the discharge pi e 8 Til rtin stand 21 u n the top of which is ippor ted a vessel 22 the vertical walls of which are of transparent material, such as lass. The vessel has a supply-pipe 23 leadng from its bottom and which has a throttle-valve 24 in connection therewith for controlling the flow of liquid therethrough. The 1pc 23 has connection with the mam supp y pipe 10. The vessel 22 has also an overflow pipe 25 that commumcates with the up or portion of the vessel and extends down t rough the stand 21 in arallel relation with the supply-pipe 23. ted conveniently within t e stand 1s a byass valve 26 connecting the supply-pi e 2 and the overflow ipe 25 through t e medium of suitable -connections 27.

In the front of the stand is a chambered protuberance 28 having a lid 29 for closing the same, and the latter has a flange 30 extending outwardly with a lid 31 hingedthereto. A push-button 32 is mounted with its stem extending through the lid 29 so as to engage an operating lever 33, the latter havin bearing connection against the stem 34 of t e valve 24. A pin 35 also 1s shdably mounted in the lid 29 with its inner and bearing a inst an o crating lever 36 wh ch is pivotal y menu and has also bearing relation against the stem 36 of the by-pass valve 26. The pin 35 is so proportioned that when the lid 31 is in closed position the valve 26 will be held open through the medium of the lever 36 an the pin 35,'thus permltting the content of the vessel 22 to pass out through the upper part of the supply-pipe 23 and the byass valve into the overflow pipe. Also the id 31 incloses the push-button 32 so that it may not be operated without openin the lid.

A condult 37 extends up through the stand 21 and leads to the magnet 20 and contains wires 38 for exciting the magnet andfor supplying a lamp 39 at the top of the'dispensing cad. An electrical switch 40 is arranged in connection with the conduit and is adapted to be closed by a plug 41 that is mounted u n the operat' lever 33 when the latter 1s ressed inwa y by applylng pressure to t e push-button 32. A bafliedisk 42 is mounted within the lower part of the vessel 22 over the upper end of the supply-pi 23 and is for the pur of causin e H uid torise evenly as e v sel is ing filed. A' discharge nozzle 43 has communication with the lower end of the vessel 22 through which the liquid is finally dispensed. a

It is the intention that the electrical wins will have connection with a suitable source of ener and the pipe 17 will have connection wit a suitable source of air under ressure. The pipe 44 communicating wit the lower part of the auxiliary tank 2 is used for the purpose of extracting foreign matter Ithat may accumulate in the bottom of the ..an

In the operation of the invention the reservoir is charged through the fill-pipe 6, and also the tank 2 and the siphon are initially filled throu h the pipe 12. By pressng upon the us -button 32 the switch 40 1s closed and t e valve 24 is opened through the medium of the lever 33 so that the magnet becomes excited with the effect that the lever 19 becomes drawn u wardly, which movement 0 ens the air-va ve 18 and rmits the ex ust-valve 16 to close. us, air-pressure enters throu h the pipe 13 into the tank 2, which forces t 1e li uid contained therein out throu h the disc arge pipe 8, the supply-pipes 0 and 23, into the vessel 2. This operation is continued until the vessel is filled to the level of the overflow pipe opening. The push-button is then reeased, the switch thereby is opened and the valve 24 is closed. Any surplus liquid flows down through the overflow pipe 25 and is carried back to the fill-pipe 6 through the pipe 7. When the switch is opened the magnet 20 drops to its normal position, together with the lever 19, causing the airvalve 18 to close and the exhaust-valve 16 to open, so that the air introduced into the tank 2 is released and discharged through the exhaust-pipe 15. When thus released of airpressure the tank becomes automatically refilled through the siphon. The liquid contents of the vessel is then dispensed through the nozzle 43 in such quantities as desired. The vertical walls of the vessel being of glass, admits observation of the liquid as it enters the vessel and as it is removed therefrom, and the patron is thus rmitted to ascertain the quantity of li ui purchased.

When the operation 0 the apparatus is to be tem raril suspended, the lid 31 is closed an lock thus concealin the push button, and the by-pass valve is t ereby held open by the pressure of the door against t pm 35 which actuates the valve through the medium of the lever 86. The contents of the vessel thereby is permitted to drain through the feed-pipe and valve into the overflow pi e 25.
